What is Gcnew in Visual C++?
gcnew is an operator, just like the new operator, except you don't need to delete anything created with it; it's garbage collected. You use gcnew for creating . Net managed types, and new for creating unmanaged types.- C++/CLI is an extension of the C++ programming language as described in ISO/IEC 14882:2003, Programming languages — C++. In addition to the facilities provided by C++, C++/CLI provides additional keywords, classes, exceptions, namespaces, and library facilities, as well as garbage collection.
